6 Claims.

Our present invention relates to a combined hot stamping and perforatingpress and to the method of simultaneously hot stamping and perforatingstationery or the like and constitutes an improvement upon the inventiondisclosed in Patent No. 1,978,790 granted to us on October 30, 1934.

The primary object of our invention is to provide a press which iscapable of use for either separately or simultaneously stamping or imprinting and perforating articles of stationery such as writing paper,announcement cards and the like to provide said articles with plain orperforated uni-colored or contrastingly colored, lustrous or metallicfoil designs, monograms, insignia,

etc. A further object is to provide a press of the character describedwhich will be inexpensive,

portable and so simple as to be efficiently operable by a person ofaverage intelligence after but a few minutes instruction as to its use.A further object is to provide novel means for automaticallysimultaneously feeding the color strip carrying the imprinting ink ormetal foil and the cushioning strip for the perforating die so as topresent fresh portions of said strips to the stamping die for eachstamping and perforating operation.

A further object is to provide a novel form of type or die for use withsuch press whereby the simultaneous hot stamping and perforating ofstationery and the like to provide the same with con trasting colordesigns can be accomplished. A

still further object is toprovide a novel method of ornamentingstationery and the like and the product resulting from such method.

Referring to the drawings, let A indicate a substantially C-shaped framecarried by and preferably formed integrally with a substantially conicalbase member B which in turn may be formed integrally with or mountedupon a supporting plate C. The upper arm of the c-shaped frame is formedwith a depending portion a. having a transverse recess 2a therethroughfor accommodating heating means preferably in the form of an electricresistance element D which is removably carried thereby. The front andrear sides of the depending portion are inclined inwardly .and upwardiyfrom the base thereof to provide a dovetail supporting and guiding meansfor a palette E which has a complemental dovetail recess. The palette isformed with a socket within which a chase F may be suitably held by aclamping screw (not shown). To facilitate the mounting and removal ofthe palette from its supporting means the palette is provided with ascrew threaded clamping handle e.

The base member B at its top supports a table b and depending from saidtable and extending centrally through said base member is a stud 21)formed with a rack for cooperation with a pinion g formed on anoperating shaft G which extends transversely through an opening in saidbase. An operating handle 2g is connected to the outer end of theoperating shaft for rotating said shaft to raise or lower the table b. Aplaten H is mounted on the table b and is movable upwardly toward thechase F as the operating handle 2g is moved downwardly. For resistingsaid upward move ment and for returning the platen downwardly on thecompletion of a stamping operation there is provided a helical coilspring J. At the rear of the platen there are mounted two plates 11.each of which carries a stud or pin 271. which extend in parallelrelation over the top face of the platen and provide guides for a gauge'bar K which at each end is formed with an opening through which thepins extend. The gauge bar may be held in any adjusted position over theplaten by thumb screws 371. or the like. A pair of spring clips k arecarried by the gauge bar K and adapted to receive and hold thestationery to be stamped and/or perforated.

Secured to the top bar of the C-shaped frame is a carrying member L nearone end of which is mounted a spindle Z extending forwardly therefromand upon which in turn is mounted a roll of color strip material M whichmay be of any desired character that will transfer colored ink ormetallic foil therefrom to an article being stamped under the influenceof heat 'and/or pressure. Suitable means may be employed for providingthe necessary frictional resistance to said roll M to permit unwindingthereof under tension. At

the opposite end of the member L upon. a depending lug thereof ismounted a spindle; 31 upon which in turn is rigidly mounted a friction.roller N. In superposed relation to the roller N is a second friction orpressure roller N" carried by an arm 51 pivoted at 51, said roller Nbeing held against the roller N under the tension of a spring Bl. Alsofixedly carried by the spindle 32 is a ratchet wheel which cooperateswith a gravity activated pawl o to cause movement of the roller N todraw the color strip m from the roll M between the rollers N and N asthe platen is raised and lowered. The pawl 0 is pivotally mounted at 20to one end of a link 30, the other end of which is pivotally mounted onthe spindle 32'. For moving the link 30 and with it the ratchet wheel 0there is provided a rod P, one end of which is fixed to the platen H andthe other end of'which is pivotally connected to the link 30intermediate its ends.

The top face of the platen H underlying the horizontal component of thecolor strip 112 is formed with a channel extending thereacross, saidchannel being of two depths 472 and 571, the latter being the deeper andextending centrally of the former. Disposed within the channel 4h so asto lie flush with the top of the platen is a plate h, which latter has arectangular opening Th underlying the chase F and a second opening 8hprovided by bending a portion 971. of the plate 6h downwardly as bestseen in Fig. '1. The plate 672. forms with the platen a longitudinallyextending recess through which is guided a cushioning strip 1" of heavypaper or the like supplied from a roll R mounted upon a support 21'extending upwardly from the supporting plate C or any othersuitable'means.

Depending from the platen H at the rear thereof and preferably inalignment with the. rod P is a bracket having a hub or bearing s nearits.

lower end. and through which extends a spindle 2s. Mounted ontherear endof said spindle is a ratchet wheel is and engaging therewith is a pawl48. Thepawl is pivotally carried by one end of a link 58, the other endof which is pivotally connected to one end of a link 6s, the other endof which in turn is pivotally connected to an. upstanding bifurcated lugls mounted on the base plate C. Th pawl 4s is held in engagement withthe ratchet wheel by a tension spring 83. Mounted upon the forwardlyextending end of the spindle 2s is'a cushion roller T. A friction rollerT mounted upon a link V pivotally connected to the depending bracket Sis held in frictional pressing engagement with the periphery of saidroller T by means of a spring U, one end of which is connected to thefree end of the link V and the other end of which is connected to thebracket S.

The cushioning strip 1' after being guidedv through the channel 5h inthe platen and. under the deflecting lip 93h passes through the frictionrollers T and T; the associated pawl and ratchet mechanism of whichserves to draw said. strip through therollers everytime the platencompletes an upward and downward movement in performing a stampingoperation.

In the operation of our press a sheet of stationery or the like W whichis to be operated upon by the stamping and perforating dies is engagedunder the clips k on the platen after the guide K has been set. In theinstant case a sheet of stationery has an area 112 of contrasting colorto the sheet and the guide K is set so as to bring this area w directlyunder the stamping dies. Now let ussuppose that it is desired toornament said paper sheet with the cut out arbitrary initials EFA and toencompass said initials in a border 219' of contrasting color to boththe paper and the area to; More specifically let us suppose that thepaper is white, the area '11) is red and the border 2w is gold so thatthe cut out initials will be: red surrounded by a border of gold. Thestamping and perforating initial dies EFA with spacing elementstherebetween will first be mounted in. the chase F and thechase thenmounted in. the palette E. The color strip m will be such. as adapted todeposit upon the paper a gold coloration when heat and pressure isapplied thereto. The individual initial and spacing dies are of thecharacter morespecifically shown .in detail in Figs. 6 to 8.

The initial dies X and spacer dies Y have cutting means a: and grespectively which are adapted to cut through or perforate the paper toleave the initials EFAfstand out. in relief- The top 2 of the chase isof less height than the cutting means a: and y but of greater heightthan the clearance or depth of said cutting means so that the top of thechase provides a a ioning strip therefore under the influence of heatand stamping pressure upon the chase will embed the cut out or scrapportions from the sheet W' and the color strip m in the surface of thecushioning stripwhich will carry said scrap portions away asfreshportions of thecolor and 01' the cushioning strips are presented tothe dies for each stamping operation. It will 7 be apparent that suchfresh portions of both the color strip and the cushioning strip will bepresented to the stamping dies after each stamping operation because ofthe feed action of the. ratchets O and 3s respectively. g V V I It willbe apparent that any color scheme of contrasting colors for theornamentation of stationery and the like can be provided by ourinvention by varying the contrasting colors of the paper and colorstripsemployed and it will be also apparent that the color strip may beused with ordinary stamping or printing dies or type and that cuttingdies may be used without or independently of any color strip. It willalso be apparent that the invention is susceptible of embodiment inother forms than herein specifically illustrated and we therefore do notwish to be limited to the details of construction shown and describedsince the-same may be changed without departing. from the spirit of theinvention as expressed in appended claims...
